Memories Are Made of This
Format: Kindle
Belle Burden has overcome a weighty burden—pun intended! Strangers is a book of many colors. There is so much of the overcast gray of heartbreak and estrangement. There is plenty of the blue of heavy disappointment and grief. But happily for every reader, there are so many of the bright colors of happiness and fulfillment. The premise of this memoir has been well documented—a wealthy, privileged life led by a woman of means is interrupted by the abrupt departure of her husband for points unknown. Children remain—-lodged in some difficult ‘tween years. Central is the woman who just happens to be made of pretty stern stuff as it turns out and who is a brilliant writer. Belle Burden is the belle of her own tale. She shares it all with the reader in un-put-down-able prose, sparing nothing, We are richer for reading Belle Burden’s beautifully crafted memoir. The warm glow of hope is there for all to share. Well done!

Surprisingly Unputdownable
Format: Kindle
I read saw several reviews that said this book wasn’t really about anything, and they were right. There was no big drama, no fighting, no headline news. But there was something in the writing that felt profound and I couldn’t stop reading. And I’m glad I didn’t.
In the end for me, this was a story about a marriage, and choices that were made and the strength of a woman who wouldn’t be silent, and the writing that brought so much emotion with it that I wound up feeling all of it so deeply. And when a writer can create those feelings in me, then her book was definitely worth reading.
I highly recommend this book - I don’t think you’ll regret the time you spend in its pages. I know I didn’t.

Slightly Interesting
Format: Kindle
First, I think Belle is a great writer. There was a lot of effort put into making this a very readable book. I also think that what happened to her really was terrible. Her husband 100% was wrong in what he did to her with the affair and his disappearance. Ultimately, her marriage prior to the betrayal seemed very superficial. She acknowledges that she chose the comforts of wealth over a close relationship. She had a part time husband/father and honestly it's not surprising that he left. He was barely there to begin.
Her absolute terror in imagining that she would drop down from the top 0.1% down to around the top 1% was not the compelling tragedy that she seems to think it is. Her bemoaning of the loss of ultra luxuries tended to diminish the emotional toll of her plight.
The book is laced through with the eventual end that her husband is going to take his assets and half of hers, but it never happens. I think she wants to relate the uncertainty and fear that she had, but it comes off as fake panic.
In the end, it's a sad story, but it was very predictable. It's a story about a woman who outsourced her responsibilities, who doesn't know how to operate without extreme wealth, and who shudders at the prospect of having to work a job. It was a short book, but 3 times longer than necessary.

Raw and Honest
Format: Hardcover
I admit I purchased this book because of all the hype, but also because I have been, since childhood, intrigued by her various family legacies (Burden, Vanderbilt, Cushing, Fairbanks), and their alliances (Whitney, Astor, Roosevelt, etc). I was not sure what to expect, but I am grateful I read this book. Being a queer man I probably am not the core audience for this book, I can attest it is still a great read.
Ms. Burden is amazingly candid and honest in a way I don't think most people in her situation would be. I can already tell that there will probably be countless reviews about how privileged her life was even during and after her divorce, and how unrelatable this book is for many people, but then you are missing something. If you want to judge Ms. Burden for things she had no control over then you should examine your own life.
My hat off to the author for being so open about such private matters in her life, and also for doing a great job shielding her children in life and in the book.
I hope it is true that there is a movie/series being made that will star Gwyneth Paltrow. I love Gwyneth, and if the author won't play herself I think Gwyneth is an amazing choice for her poise, acting ability, and class. Can't recommend this enough!
OH, I am curious to know if anyone who read this book read Wendy Burden's memoir Dead End Gene Pool. I LOVE that book, but it is so very very different, and I am curious to know if Wendy and Amanda get along irl.

My son is actually motivated to do a workbook
Format: Paperback
My Kindergartener finished homeschool online early and we have been doing a page a day and he loves it and loves to earn a sticker after each day and put it on his chart. I love how engaging the workbook is and how it introduces some 1st grade concepts. Would highly recommend.
